Abstract: The abstract explores the effects of diverse dietary compositions on haemato-biochemical parameters in lactating Murrah buffaloes, critical for India's dairy sector. Despite their significant contribution to milk production, buffaloes face challenges such as low yields due to irregular access to quality feedstuffs. The study investigates the impact of different feed compositions, particularly green fodder and concentrates mixtures, at the Buffalo farm in Hisar. The research, conducted under ethical approval, involves 18 lactating Murrah buffaloes divided into three treatment groups based on parity. Buffaloes were housed in a loose housing system and subjected to various dietary treatments: Treatment T₁ (Control) received a standard diet, while Treatments T₂ and T₃ replaced portions of green fodder with concentrate mixtures. The study spanned from 10 days postpartum to 6 months of lactation, recording parameters like body weight gain, feed intake, milk yield, and haemato-biochemical profiles. Results highlight significant variations in plasma glucose and blood urea nitrogen levels among the treatment groups. Buffaloes fed with concentrate mixtures (T₂ and T₃) exhibited increased plasma glucose concentrations, indicating heightened glucose metabolism. Moreover, elevated blood urea nitrogen levels in these groups suggest enhanced protein metabolism due to concentrate inclusion. The findings underscore the importance of tailored nutrition strategies in optimizing animal welfare and productivity. They contribute to a deeper understanding of nutrient utilization and metabolic processes in lactating buffaloes, informing evidence-based practices for sustainable dairy production. Further research could delve into specific metabolic pathways affected by dietary changes, offering insights into optimizing animal health and performance outcomes. Ultimately, these efforts aim to address nutritional deficiencies, enhance buffalo productivity, and bolster the sustainability of India's dairy sector.
